SANITARY LATHER-MING DEVIGE.

Application filed may 26, 1922. Serial 1%. 563,841.

To all whom itmay corwem:

Be it known that I, JosnrH CAMPANELLA, a citizen of the United States,residing at New York city, in the county of Bronx and 5 State of NewYork, have invented certain new and useful Improvements in a SanitaryLather-Making Device, of which the following is a specification.

It is common practice in barber shops to use a single brush for formingthe lather on the faces of difierent customers. Such a practice isobviously unsanitary and highly objectionable,'and in many places lawshave been passed requiring that the shaving brush and other utensils besterilized after each operation.

In accordance with my invention, a nozzle is provided through whichliquid soap, or other lather-forming liquid, is passed and from which itissues as lather which may be applied to the face of the customer by thehand of the barber, thereby overcoming the objections above referred to.

l have illustrated my novel form of nozzle in connection with a devicefor containing liquid soap and for forcing the same through the nozzle,which is similar to that illustrated in my prior application, Serial No.373,586, although it will be understood that the nozzle forming thesubject-matter of the present invention is not limited to use with theparticular apparatus there illustrated.

My invention will best be understood by reference to the accompanyingdrawing, the single figure of which is a vertical section, partially inelevation, through a device embodying one form of my invention.

Referring, now, to the drawing, in which all l have illustrated thepreferred form of my invention, 1 is a receptacle, preferably, thoughnot necessarily, formed of glass or other transparent material, forcontaining liquid soap or other lather-forming liquid 2. The upper endof the receptacle is constricted, at 3, to form a neck, which isscrewthreaded 'on its outer side, as at l, to receive a cap 5,'which isscrew-threaded on its inner side, as at 6, to engage the screw-thread of59 the neck 3, the cap preferably being formed integral with a head 7,which is preferably formed of a suitable metal, such, for enample, asaluminum. .The head is prov1ded with an extension 8,preferablycylindrical in form, and forming part of the nozzle, wh1ch lhave indicated generally by the reference character 9. A washer 10,, ofrubber or other flexible material, is preferably interposed between thetop of the neck 3 and y the head 7. The head is provided with a passage11 having a vertical portion communicating with the receptacle and ahorizontal portion 12 which passes through a n pple 13 formed on thehead 7. A rubber pipe 14 is attached to the nipple 13 in the mannerusual in atomizers, a compression bulb 15 being attached to the outerend of the pipe 14. The head 7 is also provided with a passage 16,having a vertical portion communicating with the receptacle 1, and ahorizontal portion 17, the horizontal portions of the two passages 11and 16 preferably being arranged in alignment, as shown,

The vertical portion of the pawage 16 is screw-threaded at its lowerend, as at 18, to receive the screw-threaded end of a pipe 19, whichpreferably extends to a point near the bottom of the receptacle 1. Aby-pass or passage 20 connects the horizontalportions 12 and 17 of thetwo described passages, and is preferably of a small diameter ascompared with said passages. The extension 8 on the head isscrew-threaded at 21 and receives the screw-threaded end of a tip 22.

The extension 8 is provided with a recess 23,

preferably cylindrical in form, adapted to receive a lather-formingdevice 2a, which comprises a plurality of lather-forming foraminousmembers 25 located side by side,

and preferably secured in a cylindrical shell 26, which is received inthe recess 23, each of the screens being of a mesh sufficiently large toprevent the liquid soap from clog= ging the same. The ends of the shell26 are preferably spun over the screens to hold the same in position,the shell and the screens forming a unitary structure. The tip 22 isprovided with a recess 27, preferably of the same diameter as the recess23 in the extension 8, and registering therewith whenthe tip is securedto said extension, as illustrated in the drawing. A second lather-foingdevice 28 similar to the one already descri is received in the recess27. A Washer 52% is preferably interposed between a shoulder 30 formed.in the tip and the outer end or the extension 8, and which also engagesthe lather-forming member 98 on its a side The two lather-formingmembers are refer: ably spaced apart by a collar 31 w 1e11 1s 4 receivedin the re'cessof the extension8.

The operation of the device embodyin my invention will readily" beun'derstoo from the foregoing descnptiomand is as follows: By pressinthe bulb 15, pressure a is created within t e receptacle 1, which lthrough the passages 16 and 17 to the nozzle,

. sage acts upon the liquid rising through the forces liquid soapthrough the pipe 19 and the small diameter of thepagssage 20 permittingsuficient pressure to be built up within the receptacle to force theliquid soap through the pipe and thepassage. At the sametime, the airpassing through the pasit desirable to use is not clear, but contains acertain amount of rather fine sediment. I have found, in practice, thata single foram inous member of sufficiently fine mesh-to form lather,quickly becomes clogged, and thescreen must then be renewed. Byproviding a plurality of lather-formingmembers located side by side, i.e., face to face, each of the members being of a mesh suflicientlycoarse to permit the soap, including the sediment, to pass, and therebypreclude 1 its becoming clogged by the liquid soap, the

lather-forming member may be used practically indefinitely withoutbecoming clogged, and, at the same time, the plurality of lather-formingmembers forms a satisfactory lather. l have found, further, that byproviding two separate sets of such members, spaced apart in the mannershown, the quality of the lather is greatly improved, as it forms a muchmore creamy lather than is formed by a single lather-forming memberhaving the same number of foraminous mem-' here as. the two membersillustrated combined. I

My theory of what takes place in the lather-forming members is asfollows: When the lather-forming liquid, such as liquid soap, mixed withthe, incoming air,'passes through the first foraminous member, the soapforms films across the various openings, the edgesof each individualfilm ad,

hering somewhat to the wires of the foraminous member. The air pressureforces the middle f the film away from the member, thereby formingindividual bubbles, and as the mixture of air and liquid passes throughthe successive foraminous members, the bubmemes bles are finely brokenup and finally issue from the nozzle in the cm of a creamy lather.Whatever the correct theory may be, however, as to how the lather isformed, I have found, in practice, that the device made in accordancewith my invention, makes a lather that is highly satisfacto WhatI claimand desire to'secure by tters Patent of the United States is:

1. In a lather-making device, a nozzle, and means for forcing a lather'forming liq uid through said nozzle, said nozzle comprising a pluralityof lather-forming foraminous members arranged face to face and incontacting relation through which the lather-forming liquid is forced inseries.

2. In a lather-making device, a nozzle comprising a plurality ofmetallic latherforming foraminous members arranged face to face and in'contacting relation through which a lather-forming liquid is forced inseries, each screen being of sufiiciently coarse mesh to preventclogging by said liquid.

3. In a lather-making device, a nozzle, and means for forcing alather-forming liquid through saidnozzle, said nozzle comprising twospaced lather-forming devices each of which comprises a plurality oflatherforming foraminous members arranged face to face through which theliquid soap is forced in series.
